Worked on improving localization reliability for the streamyfin/streamyfin repository, focusing on internationalization and configuration management using TypeScript. Addressed a critical issue where Ukrainian translation resources were not loading correctly by renaming the translation file from ua.json to uk.json and updating the corresponding language codes in the i18n configuration. This targeted fix reduced runtime errors and enhanced the user experience for Ukrainian-speaking users in multilingual deployments. Maintained high code quality through clear, actionable commit messages and thorough documentation, ensuring the repository is well-prepared for future localization enhancements while adhering to established team standards and best practices.
